I try not to compare between cities, but in this case it's hard not to. Having been to the Telus World of Science in Vancouver just last year I was expecting something like that for the Spark. Perhaps I was expecting too much or even the wrong thing, but it was so not worth the admission fee they were charging! There was literally nothing for the adults to do. It was probably fun for the kids to construct various things but that was pretty much it. My friend and I basically paid $21 each to babysit our kids at the various stations.
And oh on top of that you have to pay a $5 parking fee.
Don't think I'll be returning anytime soon...
